Abstract

In this paper

An adaptive L-filtering algorithm and its deterministic properties are discussed.Differentiating from the several proposed adaptive L-filtering algorithms based on the signal to noise ratio

the new algorithm adjusts parameters of the L-filter adaptively according to properties of time-varying signals.Theoretical analysis and simulation show that the algorithm is very efficient for edge preservation.
